    1. 3 sq = 9

    so,

    9x - 5x - 12 + 0

    4x - 12 =0

    4x = 12

    x = 12/4

    x = 3

    2. 9x + 13x + 12 = 0

    22x = -12

    x = -12/22

    x = -6/11

    3. 9 sq = 81x

    81x -42x + 40 = 0

    39x = -40

    x = -40/39

    .

    hope i helped...!!!

    It doesn't sound like you want HELP, it sounds like you want somebody to solve them FOR you. You should probably learn how to do this on your own if you want to pass your class. Just saying.

    Is there a part of the problem you don't understand how to do? Because I can help you with THAT. :)
